# Ch 31: 6th-8th Grade Math: Graphing Functions

This Graphing Functions chapter is designed to teach your 6th - 8th grade students how to graph cubics, quintics and quartics as well as how to correctly use the distance and midpoint formulas. The chapter's fun video lessons also explain linear equations, parabolas and zero slope. Test your students' progress with the multiple-choice lesson quizzes.

## 6th-8th Grade Math: Graphing Functions - Chapter Summary

The video lessons in this Graphing Functions chapter were created to assist you in teaching your 6th - 8th grade students how to convert equations to standard form, find ordered pairs and apply the x- and y-intercepts of a line. You can also demonstrate the steps for identifying increasing and decreasing functions. Use the chapter examination to assess your students' understanding of functions.
